Abstract

TECHNIQUES ARE DESCRIBED FOR ENCODING AND DECODING DIGITAL VIDEO DATA USING MACROBLOCKS THAT ARE LARGER THAN THE MACROBLOCKS PRESCRIBED BY CONVENTIONAL VIDEO ENCODING AND DECODING STANDARDS.FOR EXAMPLE, THE TECHNIQUES INCLUDE ENCODING AND DECODING A VIDEO STREAM USING MACROBLOCKS COMPRISING GREATER THAN 16X 16 PIXELS, FOR EXAMPLE, 64X64 PIXELS. IN ONE EXAMPLE, AN APPARATUS INCLUDES A VIDEO ENCODER CONFIGURED TO ENCODE A VIDEO BLOCK HAVING A SIZE OF MORE THAN 16X 16 PIXELS, GENERATE BLOCK-TYPE SYNTAX INFORMATION THAT INDICATES THE SIZE OF THE BLOCK, AND GENERATE A CODED BLOCK PATTERN VALUE FOR THE ENCODED BLOCK, WHEREIN THE CODED BLOCK PATTERN VALUE INDICATES WHETHER THE ENCODED BLOCK INCLUDES AT LEAST ONE NON-ZERO COEFFICIENT.THE ENCODER MAY SET THE CODED BLOCK PATTERN VALUE TO ZERO WHEN THE ENCODED BLOCK DOES NOT INCLUDE AT LEAST ONE NON-ZERO COEFFICIENT OR SET THE CODED BLOCK PATTERN VALUE TO ONE WHEN THE ENCODED BLOCK INCLUDES A NON-ZERO COEFFICIENT.
